fix(tracer): modify aws-xray-sdk-core import for js

[dreamorosi]

Description of your changes

This PR modifies the imports of the aws-xray-sdk-core package to accommodate customers using Powertools via JavaScript rather than TypeScript. Given that these customers don't necessarily use esbuild or other transpilers the ESM import format will case a syntax runtime error as shown in the linked issue.

The customer reporting the issue has kindly provided a workaround which seems to fix the issue and it's implemented in this PR. I have run some manual tests on my machine and the issue seems to indeed have been fixed.

@am29d if you come online before me (likely), could you please review this & make a release?

Below some ideas for the release notes, feel free to rewrite it entirely or as you see fit.

Summary
This minor release fixes a bug affecting customers using Tracer in a JavaScript ESM environment.

Tracer
In v2.0.0 we launched ESM support and most of our focus went on customers using Powertools with TypeScript and bundlers (i.e. esbuild). This introduced a bug that prevented customers using plain JavaScript with ESM from successfully importing the utility.

This release changes the way that the AWS X-Ray SDK for Node.js is imported within the Tracer utility so that customers using ESM with JavaScript can import the utility correctly.

Special thanks to @webdeveric for reporting the issue and suggesting a fix.

Good catch, thanks @webdeveric
